It also supports the fly or balance wheel 0 in the inner face of which is the other section or face 0 of the clutch.

The clutch-section C is movable lengthwise the shaft to engage and disengage the clutchsection of the balance or fly wheel. The fly or balance wheel has the beltsection 0 and beyond it upon the said shaft (-1 is a loose belt-wheel c. The member G is moved into engagement with the other member by a Spring (Z (see Fig. and out of engagement therewith bya cam d" at the end of the shaft 0 the spring and cam operating through a lover I), which is pivoted at (Z and the lower end of which is forked to engage a recessed hub of the said clutch member 1'.

The lever is connected with the cam d by a stud (1 supported by the lever, forced outwardly therefrom toward the cam by a spring, and held in said outward position by said spring and removed from the cam to permit the spring (I to move the driven member of the clutch into engagement with the driving member by the bell-crank lever d", (see Fig. 2,) pivoted at (Z to a moving link or part D, the arm (1 of which has a pin or roll rcupon its side, which is adapted to be brought into contact with the head (1 of said stud (Z in moving it outwardly and to then ride by the same to a position above or beyond it in order that it may not )e held by said stud-head from returning to a position to be immediately engaged by the stop-cam d" at or near the end of one full revolution thereon. This bell-crank lever is connected by a rod (1 with the treadle d, pivoted at d to the outer side of the frame and having a spring d to resist the downward thrust: and to restore it after its removah The head (7 preferably has the rounded surface (2, over which the pin d will ride after the stud d" has snapped back to its original or normal position. it will be seen that by means of this construction the connection of the bell-crank lever with the stud-head is broken and a repetition of the action of the machine is prevented, or, in other words, the machine can make but one reciprocation, even if the foot be kept upon the treadlc,but after the removal of the foot from the treadle the bell-crank lever and studhcad are immediately engaged, so that the machine can be again started, The tension of the clutch-spring (Z maybe varied to close the clutch with any desired force or stress de sired.

The table or bed a supports the jack E, which, broadly speaking, comprises a last or work-support (not shown) mounted upon the upper end of a spindle c, vertically movable in a stand e, which is adapted to slide in the ways c inward or outward upon the bed or table. It has an adjusting-screw by which the height of the spindle in relation to the stand and the height of the work-support can be varied, and when in operative position the lower end of the spindle is above a pressure-head E, also carried by the bed or table, contained in a hole therein above the pivotpoint e of the upper toggle-link, and adapted to have a slight vertical movement imparted to it by a cam c formed on the upper side of this link, and which maybe integral there-. with or may be made separate and attached thereto. The object of this cam is to enable the heel -blank to be brought against the tcmplet or pressure plate E with any degree of pressure or force innnediately before the awls touch the upper surface of the heel or the nails are fully driven therein.

The pressui e-head has a shoulder c", which rests upon a shoulder c. The shoe-centering devices or receiver E also comprise a part of the jack and are represented in front elevation in Fig. 1. They are like those described in the patent toKrcwson, No. 511,852, with the exception hereinafter noted, and they provide means for centering the heel end of the shoe upon the last or work-support and a back-stop for the heel. They are mounted by their common supporting-plate c upon a slide which is in turn supported by and movable upon a bracket c, attached to the table or bed by the sections 6'' c one extending upon the upper part of the table and one against the back of the frame and each taking a fastening or bolt.

The slide c has a downwardextending front e against which the lower part of the plate e is held by a fastening-screw c, the plate 0 having a vertical slot by which it may be verticallyadjustedin relation to the slide. The slide is horizontally adjusted by means of the screw 6 which screws into the bracket from behind and is operated by the handwheel c, the stud or shank of the screw being connected with the slide by a forked piece. The upper cross-head has a revolving head 1, having the arm f, supporting ablockf', carrying a gang of awls f an arm f, supporting a block j", carrying a gang or group of drivcrsj, and an armf", the under surface of which is a spanker.

The rotary head is carried by the shaft f and is turned byhandlcs (Seel ig. 1.) The shaft at its rear end is connected by a bevelgcarf (sec 1 3 and 4-) with a bevel-gear f on the vertical shaft f". The bevel-gear f has a long hub f, which extends through the box f fastened to the upper cross-head I), being attached to the box by a nut. The gear and hub move upwardlyand downwardly on the shaftj' in unison with the movement of the cross-head, and the connectionbetween the gear, hub, and the shaft maintained by a spline or fast feather/" on the shaft, which enters a corresponding recess or groove in the gear-hub. The shaft f" and its spline extend through the hubg of a skeleton plate G, (see Figs. l and 9,) which supports the nailcarrier G, the plate being attached to or corn necled with the shaft to be turned thereby and being adapted to fall and rise with it. The lower end of the shaftf is supported in IIO an upward extension e of the bracket e The skeleton plate G rests upon the upper surface of the table H, (see Figs. 4 and 10,) which supports the templet E This table spans the space between the two uprights a a of the frame and has at each side a downwardly-extending section h,which is arranged to slide upon the inner sides of said uprights. The connection between the side sections of the table and the uprights we prefer to establish by gib-plates h, set into the recesses b in the side sections, (see Fig. 5,) which gibplates have the recesses h to receive the outwardly-extending sections 77, of the upright-s, upon which the gibs and table are vertically movable. The gibs loosely fit their holdingrecesses 712, and by means of suitable ad justing-screws, which extend through the sections 72 against them, serve to fit, locate, and adjust the table in respect to the stationary sections of the frame sides. Braces 71 connect the side sections of the table with its top. Vertical movement is provided the table by means of the lever h", (see 1, 2, and 3,) connected at 77, to a rock-shaft 7Z8, carried by the bracket 6 and having at each end the arm or lever h", the ends of which are connected by links 71 with the sides h of the table. These arms are so formed or arranged that upon being moved into a vertical position they not only. serve to move downward the table H, but also to lock it in its lowest position. The table has a recess 72, (see Fig. 10,) opening from its front edge, which is substantially square in shape, for the reception of the templet E which is removable therefrom, being held therein by tongues which enter grooves 71 in the sides of the recess, (see Figs. 1 and 10,) and a button h serves to lock the templet therein. The upper surface of the templet E and table H are plane or level and the skeleton plate G is adapted to rest and turn upon it.

To enable the invention to be better understood, we will say that in the operation of the machine the shoe, having been placed upon the last or work-support, is moved into the shoe receiver beneath the templet E which is then in its highest position, (see Fig. 1,) and the heel-blank which is to be attached is placed upon the heel end of the outsole of the shoe against the back-stop and beneath the templet. The templet is then moved down upon the heel-blank, (see Fig. 4,) pressing it against the sole, by the lever 71 and locked in its lowest position by the straightening ofthe arms h and this locking movement of the lever gages or establishes the pressure to be applied to the heel, as if the lever cannot be moved down to its lowest position it is an indication that more pressure for attaching the heel will be required than is desirable. If, on the other hand, the lever goes down too easily, it will indicate that the heel will not be compressed enough. If the lever is gently forced down, it will indicate that the templet has been brought into contact with the heel-blank and that in the subsequent operation of the machine the proper pressure will be applied to it.

It is necessary that the templet and the table H be locked down preparatory to starting the machine, because the first operation of the machine is to move upward the last or work-support, and consequently the shoe and the heel, and the heel is compressed or solidified to any desired extent by being pressed upwardly against the templet. This compression is produced by the cam e working through the pressure-head E and the jack-spindle e, and its purpose is to solidify the heel and hold it solidified and clamped in advance of the pricking and nailing operations, that the heel will not be displaced during such operations and that better nailing will be done, as it is desirable that the heel be held compressed or partly compressed during the pricking of the holes therein and during the driving of the attaching-nails. the pressure to the heel above indicated is given, and is immediately followed by a descent of the awls through the holes in the templet E into the heel and their withdrawal and the stopping of the machine with the cross-head bin its highest position. The operator, without releasing the table H and templet E from their lowest position, then turns the rotary head, thereby causing the shaft f to be turned and the nail-carrier G to be moved into position over the templet, the nails being then automatically discharged from the holes of the nail-carrier into the holes of the templet and the drivers to be brought into operative position. The operator then causes another reciprocation of the gate by which the drivers drive the nails from the nail-carrier and templetinto the heel, the cross-head stopping, as before, in its highest position. The operator then moves the lever h upward, releasing the table H and the templet, which are forced upward and held in their highest position by the springs h, (represented i n Figs. 1 and 4,) and which are fastened at their upper ends, preferably to a takeup, and at their lower end to downward extensions from the table sides, comprising the rods 77, and cross-pieces h The operator then again turns the head F, moving the The machine being start-ed,

IIO

drivers and nail-carrier out of positionand the spanker-arm f into position over the templet H, and by so doing turns the shaft f, which moves the top-lift carrier and toplift-spanking plate M below the templet E thereby moving a top lift over the attached heel-blank to a position to be spanked upon its downward movement to the ends of the attachingnails which have been left protruding to receive it, and the machine is again reciprocated and the top lift applied to the heel, the machine coming to rest with the cross-head in its highest position. The operator again turns the rotary head, movihg the spanker-plate out of operative position over the heel to an operative relation to a loader and cement-applying device and the nail-carrier to a position to be iilled directly bya boyor helper-who is stationed back of the machine or from a previously-filled loader. The operator then removes the completed shoe and substitutes an unheeled shoe and heel-blank, while the assistant or boy loads the nail-carrier and feeds the top lift.

The top-lift devices comprise a plate M, (see Figs. 11 to 14,) which is detachably secured to the arms in of a rotary holder on, attached to the shaft f, a top-lift receiver, and a top lift holder. The plate M is a spanker-platethat is, it spanks the top lift upon the attached heel-blank of the boot or shoe. It may be used for applying a top lift or for spanking the top of a flush-nailed heel, when a thicker plate would be used than for blind-nailing, or it may be used for spanking the heel end of a spring-heel shoe, when a plate having a cavity of the shape of the spring-heel would be employed. Ordinarily for blind-nailing there are attached to the rotary plate on the top -lift holders m m (Shown in dotted lines in Figs. 5 and 12 and full lines in Fig. 13.) These are pivoted at m m, respectively, to the under surface of the plate on, and they are connected together in line with their pivots by the gear-teeth in", formed on each. They are closed and held closed by the spring m connecting their forward ends. The plate m also carries the backstop m which is adjustable thereon between the fingers by means of the adjusting-screw m, which screws in the threaded section in of the stop and which turns in and is supported by the shaft f. (See Figs. 7 and 8 and 11 to 1-1.) The plate M is attached to the arms in and plate in by pins m, which enter holes in the edge, the pins in the arms 021 being movable outwardly and being pressed and held closed by springs m attached to the arms. These toplift holding and transferring devices are movable from a position in line with the top-lift holding and feeding devices to aposition under the templet E and upon the turning of the revolving head to move the awls and drivers out of operative position.

A top lift is fed to the fingers or holders in m from the top-lift stack N by the feeding plate or slide '72, which is moved inward upon the table or support a between the top-liftholding fingers at m The top lift opens the arms or fingers and passes between them until its back end comes into contact with the V back-stop m. 'This feeding-plate has the shoulder 12?, preferably slightly undercut, against which the breast of the top lift rests as it is being fed from the stack to the tingers, and the spring a attached at a to the inner end of the feeding-plate n and to table it, serves to withdrawautomatically the feeding-plate at the end of its inward feeding movement, or from the position shown in Fig. 7 to that shown in Fig. 8.

The nail-carrier and top-lift devices at the end of the attaching operation are by the operator moved to the position represented in Fig. 5 or Fig. Gthat is, the top-lift spanker and receiver and the nail-carrier are in a position to receive a top li ft and be loadedand this is done by the boy or attendant, who pushes in the slide a to feed the top lift and places the nails directly into the holes of the nail-holding plate G or supplies them with nails from a secondary nail-holder previously loaded.

It is desirable that the support a, the slide 02, and top-lift stack N be downwardly yielding in order that no damage be done the parts in case the slide a should not have been withdrawn from under the top-lift-spanking plate before the templet is moved down, and we have represented the support a as attached to the bracket n, projecting from one of the uprights of the frame, by means of a link if and springs a (See Fig. The link forms a joint which permits the support to move downwardly and in opposition to the springs a The springs serve to move the support upwardly and hold it in its highest position. These springs may also yield slight-1y upon the feeding of the top lifts to the arms or fingers m m, especially if they are of extra thickness. The slide it is made long and provided with a handle or knob 11, by which it is adapted to be moved by hand.

)Ve have represented in Fig. 5 the top-lift stack at the back of the machine, but not at the extreme back. This is the position which it should occupy when the machine is adapted to prick the heels, as well as to drive the attaching-nails and apply a top lift, as this requires an additional set of implements, namely, awls. If the heel does not require to be pricked, the awls may be dispensed with and the cross-head may then have but two reciprocations to attach the heel and spank the top lift, and, being so organized, the toplift stack N and feed 42 and the nail-supplying devices will then be in line with each other and at the extreme back of the machine, or as represented in Figs. (5, 16, 17, and 18. The top-lift stack N is composed of the back plate it which is preferably in the form of a V and cast integral upon the end of its holding-arm a ,(see Fig. 5,) the arm being bent atits end to a right angle and being fastened at n to the support n". The stack also has the front plate a, which projects upward from a bracket 02., (see Figs. 3, 5, and 14,) arranged upon the side a of the support n to slide thereon, being fastened thereto in any desired position by the fastening-screw n Paste,glue,or other adhesive material. is supplied on the under surface of the top lift automatically during the downward movement of the table II to clamp the unattached heel upon the shoe preparatory to starting the machine. This downward movement, as above stated, also moves downwardly the top-lift spanking plate and holding devices, and during this downward movement a glue-applying device is caused to be moved upward from a glue-pan held upon a shelf 0, extending outward from the bracket 6 and from the position represented in Fig. 7 to the position represented in Fig. 8, where it is represented in contact with the under surface of the top lift 0 held by the top-lift arms m m This applies anything contained in the pan in the nature of an adhesive substance to the under surface of the top lift. \Ve prefer to use a glue-applying device made of a metal having some spring, like sheet-brass, and in the form of a curved tongue, as represented in Fig. '7. It isattached to a shaft 0 extending across the top of the pan, and is operated by means of an arm or lever 0 extending from this shaft, link 0 and sector 0 pivoted at 0 and connected by the link 0 with the arm 0 extending from the shaft k to which the table-movin g lever 7t is secured.

The plate G has a circular rim that means may be provided whereby the nail-carrier and top-lift spanker and awls,drivers,and spanker may be respectively locked in operative position as well as in the loading positions of the nail-carrier and top-lift carrier. For the sake of lightness we prefer to make the plate open, or in the form of a skeleton, and to form in it the square or other-shaped holes 9 g (see Figs. 5 and 9,) into which the awlcarrying block and the spanker-block descend when they are in operative position.

The nail-carrier G is in the form of a movable block, and is adapted to slide into its holding recess or space 9 and it is held therein by tongues formed upon its sides, which enter grooves on each side of the said recess 9 and locked in posit-ion by a spring-pin (See Fig. 5.)

The outer edge 9 of the plate is circular, and it has cut in it three pairs of reverselyarranged notches g g, which receive the ends of the oppositely-acting pawls g g respectively. (See Fig. 5.) The pawl g is pivoted at g to the table H, and has the rearward- I extending arm 9 the oflice of which will be later explained, and a closing-spring g and it is automatic in its action, closing into the notch g as the notch is moved up to it. The pawl g is pivoted to the table II at 9 It has the closing-sprin g 9 and the thumb-piece 9 It will be understood that this pawl automatically latches the plate in connection with the pawl 9 the plate being positively held between them, but to unlatch the plate the pawl must be moved from contact with the shoulder 9 It will also be understood that these pawls also lock the rotary head F in operative position, and that to turn it and the nail-carrier and top lift it is necessary to move the pawl g from contact with the shoulder g After it has been so moved and the plate G turned slightly the pawl may be released and the turning continued until both pawls g 9 make automatic engagement with the next pair of notches, fastening in operative position the next set of operating devices.

l/vhere there are three sets of operative devices, as in Fig. 5, there are three sets of notches. here there are two sets, as in Figs. 6 and 16, there are two sets only of the notches. It is desirable that the machine should not be started unless the parts which so operate are in operative relationthat is, unless the pawls have each engaged their respective notchesand to prevent the machine from being operated when the parts are not in operative relation we have provided the pawl g with the arm 9 and have connected the treadle therewith by means of the rod 9 (see Figs. 1 and 2,) the bell-crank g pivoted at g", a link 9 and a latch g pivoted at g to the front of the table 11, and which is in line with the said arm g if the pawl g is not seated in its notch. It can only be seated in its notch when the machine is in operative position. At all other times the arm 9 is in front of the latch 9 (see Fig. 16) and acts as a barrier to prevent the treadle being depressed and the machine operated. Nails may be fed to the holes in the nail-carrier G directly or from either of the loaders P P". (See Fig. 5.) Each of these holders is in the form of a plate. The plate P has the ear p, which removably secures it to a pivot 19' at the end of the bracket 19 and the plate P has an car 19 which removably connects it with a similar pivot. These loaders are located as represented in Fig. 5, and they are each adapted to be moved over the nail-carrier G to feed nails thereto. Each plate may be removed from its pivot by being lifted therefrom, and each plate may have the nailholding holes 19 arranged directly therein or may be shaped to receive a detachable nailholding block. Each nail-loader has on its under surface a slide 19 which is adapted to be drawn out to release the nails after the loader has been moved over the nail-carrier. Each of the nail-loaders P P has an ear P (see Fig. 5,) which are so placed as to come in contact with each other when the loaders are in position to be loaded or as represented in Fig. 5.

It will be understood that each loader is adapted to be turned upon its pivot to a position over the nail-carrier G when the nailcarrier is opposite them or in the posit-ion shown in Fig. 5, and the registering or proper position of each loader is determined by the contact of the edge 19 of one with the surface 1) of the other about its pivot-point. Each loader being swung around on its pivot over the nail-carrier G until the part 19 comes in contact with the part 19 will bring the holes into registering position with the holes of the nail-carrier. 5

It will be further understood that these loaders are generally loaded by the attendant in advance and that the last movement by the operator before removing a heeled shoe ITO and jacking an unheeled one to move the nail-carrier to the position represented in Fig. 5, and that the attendant then turns one or the other of the two loaders upon its pivot over the nail-carrier and removes the slide cover-plate, permitting the nails to fall into the nail-carrier.

It will be understood that nails may be directly fed to the holes of the carrier if the loaders are not used and that by the use of two leaders two attendants can be employed in sticking nails therein. This is of advantage when a relatively large number of nails is used for attaching each heel. The rotary plate G is also adapted to lock in succession two of the arms of the rotary head F, namely, the arm carrying the awls and the arm carrying the drivers, during the lower part of the reciprocation of each, by means of the locking extensions R at the back of said arms and the locking-recesses R in the uprights r '2", etc tending upward from the plate to a position sufliciently high to permit an engagement to take place between the said locking extension and the locking-recesses before the awls or drivers enter the holes of the templet or nailcarrier.

In Figs. (3,10, 17, and 18 we have shown the nail-feeding and top-lift-loading devices as applied to a two-motion machine, but? before describing them we will say that in a threemotion machine the nailcarrier is not moved over the templet to feed the nails thereto until the templet has been depressed and the heelblank lifted firmly against it, and it thereby becomes possible to discharge the nails from the nail-carrier into the templet by means of a slide-plate, which is actuated by pins upon the templet; or table If to move it sufficiently to uncover the holes as the carrier approaches the templet and to move it to cover the holes as the carrier is moved away. In a two1no tion machine the nail-carrier is moved over the templet before it is moved down, and consequently the nails must be held in the carrier until the templet is depressed, and this calls fora somewhat different mechanism for moving the cover-plate of the said nail-carrier, and we prefer to use the device represented in Fig. (5, which will move the coverplate sufficiently to uncover the holes of the carrier during the downward movementof the templet and nail-carrier preparatory to driving the nails, the said cover-plate being closed upon the upward movement of the templet and nail-carrier by a spring.

The nail-loading devices which we prefer to employ with the two-motion machine comprises the pivoted loaders S 5. (See 13" and 16.) These loaders have ears through which screws or pivots s, attaching them to a plate 8*, extend. These ears are so arranged and pivots so placed that the two loaders may be moved away from each other to receive the nails, as represented in Fig. 10, and instead of delivering the nails directly to the nailcarrier they are adapted to deliver them to the nail-holder S which preferably is formed in the plate S" and which is so located as to be over the nail-carrier when the top-lift plate has been moved into position beneath the templet and the machine comes to rest.

The two loaders S S are attached to the plate S to be removable from the pins s, which hold the plate 5" in registering or operating position, the three parts, namely, the two leaders and. the holder, constituting a set which are removed to permit loaders and holders having a different arrangementof holes to be substituted.

Each of the loaders has a slide-hole-covering plate .9, adapted to be moved in opposition to the spring .5 by the extension in uncovering the holes when the loader is in discharging position or that represented in Fig. (I, the extension forming a sort of thumb or linger piece, against which pressure may be applied by the hand in moving the plate inward in opposition to the spring, and upon the removal of the pressure the spring returns the coverplate to its original position, closing the holes.

The nailcarrier G takes its nails automatically from the vnail-holder S", moving its cover-plate T automatically to uncover the holes as it comes to a registering position beneath it. This is accomplished by connecting the cover-plate T with a dog or lever (see Figs. 17 and 18,) which is pivoted at t to the plate 8 and which by means of the spring 1 connecting one end of it with the said plate S holds the cover-plate of the holder normally closed. This lever projects into the path of a tappet 6 carried by the revolving nail-carrier plate, the end I of which comes into contact with the side of the dog or lever A (see Fig. 17) and moves it sufficiently to cause it to operate the cover-plate. As the nail-carrier plate may be moved downward before the tappet is moved horizontally from engagement with the said lover or dog we have hinged or pivoted it at 6", so that its end i will move downwardly in opposition to the spring t, and therefore if the said nailearrier plate is moved downward and again released, so that the tappet is disengaged from the lover or dog, the cover-plate of the holder will be closed by the movement of the lever, and the tappet, upon the upward movement of the nail-carrier plate, will come in contact with the under surface of the lover or dog instead of its edge and will then yield downwardly and will not operate the lever or dog.

The cover-plate of the nail-carrier G used upon a two-motion machine adapted to be moved upon the downward movement of the nail-carrier to open the holes therein when the nail-carrier is in registering position with the templet by means of a rod 1', carried by the nail-carrier plate, the end a of which (see Fig. 6) projects sufficiently to come into line ICC with a frame side at a or some stationary projection, whereby during the vertical movement of the plate the rod is moved inward.

The rod is connected at its inner end with the slide cover-plate movable crosswise the nail-carrier in a dovetail recess in its under surface, the rod having an end entering a hole in said plate, and this movement is in opposition to the spring M, which surrounds the rod, and upon the movement of the nailcarrier from its position over the templet this spring serves to move the rod outward, and therefore the cover-plate to a closing position. It will be seen, therefore, that with the construction represented in Figs. 6, 16, 17, and 18 the nail-carrier is discharged automatically after the carrier has been moved into operative position over the templet by a downward movement thereof, that when moved from such position the cover-plate closes, that as the carrier is moved under the nail-holder s a gang of nails is automatically fed to it, the movement of the carrier automatically opening the cover-plate of the holder, and that as the carrier leaves the holder its cover-plate is automatically closed, whether such leaving be by a down ward move ment of the carrier or an onward movement of it. The plate S has a stop 5 against which each of the loaders is adapted to be moved in registering them or their holes over the holes of the holder S The dog or lever 1, connected with the cover-plate of the holder S has an upwardly-extending pin 5 which serves as a handle by which the plate may be moved by hand to uncover the holes in said holder.

In Fig. 6 the loader S is represented in discharging position over the nail-holder, the nail-holder S being shown in receiving position. This form of holder can be used in connection with the three-motion organization or that represented in Fig. 5, if desired. The two-motion organization permits the toplift loader N to be placed at the extreme back of the machine and in line with the nail-holder S and nail-carrier, (see Figs. 6 and 16,) and this is considered to be a very desirable location for it, because it brings it into such close relation with the nail-loaders that theyare all easily within the control of a single attendant. The top-lift loader is like the one already described, and varies from it only in point of location.

Vith the two-motion construction the same bracket supports both the nailloading mechanism and the top-lift loader. (See Fig. 6.)

The operation of the machine has been fully described in connection with the description of its various parts.

In the operation of the machine the boot or shoe is mounted upon the last or work-sup- ,port and moved into position beneath the pressure-plate or templet E and over the pressure-head E. The heel is placed upon the sole of a boot or shoe between it and the pressure or templet plate and said plate then moved toward it, clamping it against the sole upon the last or work-support with any desired stress. The machine is then set in operation and the heel blank consolidated against the pressure or templet plate by the upward movement of the pressure-head E, and the awls, if they be used, immediately enter the heel so compressed and form holes therein. If the awls are not used, the drivers act to drive the nails fed to the templet by the nail-carrier into the heel-blank, and the driver-holding block coming in contact with the top of' the nail-carrier may serve to impart additional compression to the heel-blank while it is being nailed. The templet or pressure plate is then released, the nail-carrier moved out of operative position, and the toplift carrier into operative position under the pressure or templet plate E and over the templet and the top lift applied by the spanking action-of the spanker f, acting through the templet and top-lift carrier.
